Spraycoat Fire Rated Spray Foam Insulation (480 Sq.Ft.) - Energy

Our review of Spraycoat Fire Rated Spray Foam Insulation finds it best suited for contractors and serious DIYers who need a durable, high-performance closed cell foam with a Class-A fire rating. The single biggest reason to buy is its combination of flame resistance and long-term thermal performance: the foam forms a rigid, airtight seal that improves energy efficiency and resists settling, making it a practical choice for roofs, walls, basements and tanks where both safety and insulation value matter.

Key Features

• Class-A fire rating: Provides advanced flame resistance under ASTM E84, improving safety for roof and wall assemblies.
• Energy saving formula: Closed cell polyurethane reduces heat transfer and can cut heating and cooling costs when installed properly.
• Durable structural foam: Cures into a rigid, dense material that resists cracking, shrinking and settling to maintain thermal and acoustic performance over time.
• Dual-nozzle application: Two interchangeable nozzles let users switch between vertical wall and ceiling spraying for more consistent coverage and less dripping.
• Wide material compatibility: Adheres to drywall, wood, concrete, metal, PVC and more, making it suitable for residential, industrial and marine projects.
• Paintable and stable: Maintains dimensional stability around frames and can be painted after full cure, though UV may slightly alter color.

Who It's For

This product is aimed at professionals and experienced DIY installers who need a high-performance closed cell spray foam that offers both a Class-A fire rating and durable structural insulation. It works well on large areas like attics, wall cavities, roofs and even tanks where a consistent airtight seal and long-term stability matter.

It is less suitable for casual users expecting a complete kit; the gun and cleaner are not included and some buyers reported mixed experiences with nozzle quality and adhesion in particular installations, so those seeking a plug-and-play small patch solution should consider pre-packaged kits that include an applicator.

Pros & Cons

Pros

• Class-A fire rating and closed cell structure increase safety and reduce thermal loss.
• High coverage and value for money when applied correctly, offering significant energy savings.
• Durable, rigid cure that strengthens the building envelope and resists settling.
• Versatile adhesion to many substrates, suitable for marine and industrial use.

Cons

• No applicator gun or cleaner included, so additional purchases are required for installation.
• Some customers report mixed nozzle quality and occasional adhesion issues depending on substrate preparation.

Our Verdict

Spraycoat is a strong choice for anyone needing a long-lasting, fire resistant closed cell spray foam that improves energy efficiency and strengthens assemblies. Professionals and committed DIYers will appreciate the coverage, rigid cure and broad substrate compatibility, though you should budget for an applicator and take care with surface prep to avoid adhesion issues. Overall, it delivers good value for medium to large insulation projects.

Frequently Asked Questions

Does this kit include a spray gun and cleaner?
No. The product ships without a gun or cleaner, so an applicator and any cleaning solvent must be sourced separately.

Can it be used on exterior walls and roofs?
Yes. The closed cell foam and Class-A fire rating make it suitable for roofs and exterior wall cavities, but UV exposure may slightly change surface color.

Is the cured foam paintable?
Yes. The foam can be painted after it fully cures and is dimensionally stable around frames and openings.
